This paper mainly introduces the spectrophotometer determination of silicon in steel and alloy, manganese, phosphorus content improved method, because the national standard method when measuring sample treatment process is complex, and some of the experimental method, the sensitivity is not high, the linear relationship is poor, it is very necessary to study a fast and high accuracy method to determination of iron steel and alloy of silicon, manganese, phosphorus content. The purpose of this experiment is to select the appropriate method of treatment of samples, using spectrophotometric method to realize in a sample of three elements at the same time, fast, accurate measurement, developed for the rapid determination of silicon in steel and alloy, manganese, rapid determination of phosphorus content. By experimental study that, using NaOH-Na2O2fusion method in muffle furnace high temperature calcined sample melting, can make the steel samples dissolved completely, improve the determination accuracy. Furthermore, through the test of different color acidity on Si, Mn, P, elements of color effects, we can explore the best color acidity, make the experiment of chromogenic conditions are optimized, so as to achieve rapid, accurate determination of silicon in steel and alloy, manganese, phosphorus content of.是中翻英么?
